dir: /ChangeLog/
2008-08-18 suzuki toshiya <[email protected]>
* src/sfnt/ttcmap.c (tt_cmap2_validate): Skip the validation of
sub-header when its code_count is 0. Many Japanese Dynalab fonts
include such empty sub-header (code_count == 0, first_code == 0
delta == 0, but offset != 0 ) as the second sub-header in SJIS
cmap.
2008-08-04 Werner Lemberg <[email protected]>
* src/type1/t1tokens.h: Handle `ForceBold' keyword. This fixes
Savannah bug #23995.
* src/cid/cidload.c (parse_expansion_factor): New callback function.
(cid_field_records): Use it for `ExpansionFactor'.
* src/cod/cidtoken.h: Handle `ForceBold' keyword.
Don't handle `ExpansionFactor'.
2008-08-04 Bram Tassyns <[email protected]>
* src/cff/cffparse.c (cff_parse_fixed_scaled): Fix thinko which
resulted in incorrect scaling. This fixes Savannah bug #23973.
2008-08-04 Werner Lemberg <[email protected]>
Be more tolerant w.r.t. invalid entries in SFNT table directory.
* src/sfnt/ttload.c (check_table_dir): Ignore invalid entries and
adjust table count.
Add more trace messages.
(tt_face_load_font_dir): Updated.
2008-07-30 Werner Lemberg <[email protected]>
* src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer
assume that the first argument on the stack is the bottom-most
element. Two reasons:
o According to people from Adobe it is missing in the Type 2
specification that pushing of additional, superfluous arguments
on the stack is prohibited.
o Acroread in general handles fonts differently, namely by popping
the number of arguments needed for a particular operand (as a PS
interpreter would do). In case of buggy fonts this causes a
different interpretation which of the elements on the stack are
superfluous and which not.
Since there are CFF subfonts (embedded in PDFs) which rely on
Acroread's behaviour, FreeType now does the same.
2008-07-27 Werner Lemberg <[email protected]>
Add extra mappings for `Tcommaaccent' and `tcommaaccent'. This
fixes Savanna bug #23940.
* src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): Rename to...
(EXTRA_GLYPH_LIST_SIZE): This.
Increase by 2.
(ft_wgl_extra_unicodes): Rename to...
(ft_extra_glyph_unicodes): This.
Add two code values.
(ft_wgl_extra_glyph_names): Rename to...
(ft_extra_glyph_names): This.
Add two glyphs.
(ft_wgl_extra_glyph_name_offsets): Rename to...
(ft_extra_glyph_name_offsets): This.
Add two offsets.
(ps_check_wgl_name, ps_check_wgl_unicode): Rename to...
(ps_check_extra_glyph_name, ps_check_extra_glyph_unicode): This.
Updated.

2008-07-26 Werner Lemberg <[email protected]>
* src/cff/cffgload.c (cff_decoder_prepare,
cff_decoder_parse_charstrings): Improve debug output.
2008-07-22 Martin McBride <[email protected]>
* src/sfnt/ttcmap.c (tt_cmap4_validate, tt_cmap4_char_map_linear,
tt_cmap4_char_map_binary): Handle fonts which treat the last segment
specially. According to the specification, such fonts would be
invalid but acroread accepts them.
2008-07-16 Jon Foster <[email protected]>
* src/pfr/pfrdrivr.c (pfr_get_advance): Fix off-by-one error.
* src/base/ftcalc.c (FT_MulFix): Fix portability issue.

* src/truetype/ttpload.c (tt_face_load_loca): Handle buggy fonts
where num_locations < num_glyphs. Problem reported by Ding Li.
2008-07-05 Werner Lemberg <[email protected]>
Since FreeType uses `$(value ...)', we now need GNU make 3.80 or
newer. This fixes Savannah bug #23648.
* configure: zsh doesn't like ${1+"$@"}.
Update needed GNU make version.
* builds/toplevel.mk: Check for `$(eval ...)'.
* docs/INSTALL.GNU, docs/INSTALL.CROSS, docs/INSTALL.UNIX: Document
it.
2008-07-04 Werner Lemberg <[email protected]>
* src/raster/ftraster.c (Draw_Sweep): If span is smaller than one
pixel, only check for dropouts if neither start nor end point lies
on a pixel center. This fixes Savannah bug #23762.
2008-06-29 Werner Lemberg <[email protected]>
* Version 2.3.7 released.
=========================
Tag sources with `VER-2-3-7'.
* docs/CHANGES, docs/VERSION.DLL: Update documentation and bump
version number to 2.3.7.
* README, Jamfile (RefDoc), builds/win32/visualc/index.html,
builds/win32/visualc/freetype.dsp,
builds/win32/visualc/freetype.vcproj,
builds/win32/visualce/index.html,
builds/win32/visualce/freetype.dsp,
builds/win32/visualce/freetype.vcproj: s/2.3.6/2.3.7/, s/236/237/.
* include/freetype/freetype.h (FREETYPE_PATCH): Set to 7.
* builds/unix/configure.raw (version_info): Set to 9:18:3.
* docs/release: Updated.
2008-06-28 Werner Lemberg <[email protected]>
* src/ftglyph.c (FT_Matrix_Multiply, FT_Matrix_Invert): Move to...
* src/ftcalc.c: Here. This fixes Savannah bug #23729.
2008-06-27 Werner Lemberg <[email protected]>
* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
Horizontal_Gray_Sweep_Drop): Test for intersections which
degenerate to a single point can be ignored; this has been confirmed
by Greg Hitchcock from Microsoft. (This was commented out code.)
2008-06-26 Werner Lemberg <[email protected]>
Improve navigation in API reference.
* src/tools/docmaker/tohtml.py (html_header_3): Renamed to...
(html_header_6): This.

html_header_5t): New strings.
(toc_footer_start, toc_footer_end): New strings.
(HtmlFormatter::html_header): Updated.

(HtmlFormatter::toc_enter): Use `html_toc_header'.
(HtmlFormatter::toc_exit): Print proper footer.
Convert ~ to non-breakable space.
* src/tools/docmaker/tohtml.py (make_html_para): Implement it.
Update header files accordingly.
2008-06-24 suzuki toshiya <[email protected]>
* builds/unix/configure.raw: Check type `ResourceIndex' explicitly
and define HAVE_TYPE_RESOURCE_INDEX if it is defined. Mac OS X 10.5
bundles 10.4u SDK with MAC_OS_X_VERSION_10_5 macro but without
ResourceIndex type definition. The macro does not inform the type
availability.
* src/base/ftmac.c: More parentheses are inserted to clarify the
conditionals to disable legacy APIs in `10.5 and later' cases. If
HAVE_TYPE_RESOURCE_INDEX is not defined, ResourceIndex is defined.
2008-06-24 Werner Lemberg <[email protected]>
* src/truetype/ttinterp.c (Ins_SCANTYPE): Don't check rendering
mode.
* src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph,
Draw_Sweep): No-dropout mode is value 2, not value 0.
(Draw_Sweep): Really skip dropout handling for no-dropout mode.
2008-06-24 Werner Lemberg <[email protected]>
* src/psaux/psobjs.c (t1_builder_close_contour): Don't add contour
if it consists of one point only. Based on a patch from Savannah
bug #23683 (from John Tytgat).
2008-06-22 Werner Lemberg <[email protected]>
* src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff
with IS_HINTED.
* docs/CHANGES: Updated.
2008-06-22 suzuki toshiya <[email protected]>
* builds/unix/configure.raw: If CFLAGS has `-isysroot XXX' option
but LDFLAGS does not, import it to LDFLAGS. The option is used to
specify non-default SDK on Mac OS X (e.g., universal binary SDK for
Mac OS X 10.4 on PowerPC platform). Although Apple TechNote 2137
recommends to add the option only to CFLAGS, LDFLAGS should include
it because libfreetype.la is built with -no-undefined. This fixes a
bug reported by Ryan Schmidt in MacPorts,
http://trac.macports.org/ticket/15331.
2008-06-21 Werner Lemberg <[email protected]>
Enable access to the various dropout rules of the B&W rasterizer.

rasterizer.
* include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS,
FT_OUTLINE_EXCLUDE_STUBS): New flags for for FT_Outline.
* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the
OpenType specification.
Fix mode 4 computation.
(Render_Glyph, Render_Gray_Glyph): Handle new outline flags.
* src/truetype/ttgload.c (TT_Load_Glyph) Convert scan conversion
mode to FT_OUTLINE_XXX flags.
* src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check.
2008-06-19 Werner Lemberg <[email protected]>
* src/cff/cffobjs.c (cff_face_init): Compute final
`dict->units_per_em' value before assigning it to
`cffface->units_per_EM'. Otherwise, CFFs without subfonts are
scaled incorrectly if the font matrix is non-standard. This fixes
Savannah bug #23630.
* docs/CHANGES: Updated.
2008-06-19 Werner Lemberg <[email protected]>
* src/type/t1objs.c (T1_Face_Init): Slightly improve algorithm fix
from 2008-06-19.
2008-06-18 Werner Lemberg <[email protected]>
* src/type/t1objs.c (T1_Face_Init): Fix change from 2008-03-21.
Reported by Peter Weilbacher <[email protected]>.
* docs/CHANGES: Updated.
2008-06-15 George Williams <[email protected]>
* src/otvalid/otvgpos.c (otv_MarkBasePos_validate): Set
`valid->extra2' to 1. This is undocumented in the OpenType 1.5
specification.
2008-06-15 Werner Lemberg <[email protected]>

builds/win32/visualc/freetype.dsp,
builds/win32/visualc/freetype.vcproj,
builds/win32/visualce/index.html,
builds/win32/visualce/freetype.dsp,
builds/win32/visualce/freetype.vcproj: s/2.3.5/2.3.6/, s/235/236/.
* include/freetype/freetype.h (FREETYPE_PATCH): Set to 6.

`clazz->done_face'.
2008-06-09 VaDiM <[email protected]>
Support debugging on WinCE. From Savannah patch #6536; this fixes
bug #23497.
* builds/win32/ftdebug.c (OutputDebugStringEx): New function/macro
as a replacement for OutputDebugStringA (which WinCE doesn't have).
Update all callers.
(ft_debug_init) [_WIN32_CE]: WinCE apparently doesn't have
environment variables.
2008-06-09 Werner Lemberg <[email protected]>
* README.CVS: Updated.
* builds/unix/configure.raw, builds/unix/freetype-config.in: Updated
for newer versions of autoconf and friends.
2008-06-08 Werner Lemberg <[email protected]>
* src/type1/t1parse.h (T1_ParserRec): Make `base_len' and
`private_len' unsigned.
* src/type1/t1parse.c (read_pfb_tag): Make `asize' unsigned and read
it as such.
(T1_New_Parser, T1_Get_Private_Dict): Make `size' unsigned.
* src/base/ftstream.c (FT_Stream_Skip): Reject negative values.
* src/type1/t1load.c (parse_blend_design_positions): Check `n_axis'
for sane value.
Fix typo.
* src/psaux/psobjs.c (ps_table_add): Check `idx' correctly.
* src/truetype/ttinterp (Ins_SHC): Use BOUNDS() to check
`last_point'.

`maxTwilightPoints'.
2008-06-06 Werner Lemberg <[email protected]>
* src/truetype/ttinterp.c (Ins_IP): Handle case `org_dist == 0'
correctly. This fixes glyphs `t' and `h' of Arial Narrow at 12ppem.
2008-06-03 Werner Lemberg <[email protected]>
* include/freetype/ftcache.h (FTC_FaceID): Change type back to
FT_Pointer. Reported by Ian Britten <[email protected]>.
2008-06-02 Werner Lemberg <[email protected]>
Emit header info for defined FreeType objects in reference.
* src/tools/docmaker/content.py (re_header_macro): New regexp.
(ContentProcessor::__init__): Initialize new dictionary `headers'.
(DocBlock::__init__): Collect macro header definitions.
* src/tools/docmaker/tohtml.py (header_location_header,
header_location_footer): New strings.
(HtmlFormatter::__init__): Pass `headers' dictionary.
(HtmlFormatter::print_html_field): Don't emit paragraph tags.
(HtmlFormatter::print_html_field_list): Emit empty paragraph.
(HtmlFormatter::block_enter): Emit header info.
2008-06-01 Werner Lemberg <[email protected]>
* include/freetype/config/ftheader.h (FT_UNPATENTED_HINTING_H,
FT_INCREMENTAL_H): Added.
2008-05-28 Werner Lemberg <[email protected]>
* src/tools/docmaker/sources.py (SourceBlock::__init__): While
looking for markup tags, return immediately as soon a single one is
found.
2008-05-28 Werner Lemberg <[email protected]>
* src/truetype/ttinterp.c (Ins_MD): The MD instruction also uses
original, unscaled input values. Confirmed by Greg Hitchcock from
Microsoft.
2008-05-27 Werner Lemberg <[email protected]>
* src/tools/docmaker/tohtml.py (block_footer_start,
block_footer_middle): Beautify output.
2008-05-25 Werner Lemberg <[email protected]>
* src/raster/ftraster.c (fc_black_render): Return 0 when we are
trying to render into a zero-width/height bitmap, not an error code.
* src/truetype/ttgload.c (load_truetype_glyph): Move initialization
of the graphics state for subglyphs to...
(TT_Hint_Glyph): This function.
Hinting instructions for a composite glyph apparently refer to the
just hinted subglyphs, not the unhinted, unscaled outline. This
seems to fix Savannah bugs #20973 and (at least partially) #23310.
2008-05-20 suzuki toshiya <[email protected]>
* src/base/ftmac.c (FT_New_Face_From_Suitcase): Check if valid
`aface' is returned by FT_New_Face_From_FOND(). The patch was
proposed by an anonymous reporter of Savannah bug #23204.
2008-05-18 Werner Lemberg <[email protected]>
* src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after
correction for pixel boundary. Without this patch, the effect can
be cumulative under certain circumstances, making glyphs taller and
taller after each call. This fixes Savannah bug #19976.
2008-05-18 Werner Lemberg <[email protected]>
* src/base/ftdebug.c (FT_Message, FT_Panic): Send output to stderr.
This fixes Savannah bug #23280.
* docs/CHANGES: Updated.
2008-05-18 David Turner <[email protected]>
* src/psnames/psmodule.c (ft_wgl_extra_unicodes,
ft_wgl_extra_glyph_names, ft_wgl_extra_glyph_name_offsets,
ps_check_wgl_name, ps_check_wgl_unicode): Use `static' to make
declarations non-global.
* src/type1/t1load.c: Add missing comment.
2008-05-17 Sam Hocevar <samh>
* src/truetype/ttgload.c (TT_Load_Simple_Glyph): Handle zero-contour
glyphs correctly. Patch from Savannah bug #23277.
2008-05-16 Werner Lemberg <[email protected]>
* docs/CHANGES: Updated.
2008-05-16 Sergey Tolstov <[email protected]>
Improve support for WGL4 encoded fonts.
* src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): New macro.
(ft_wgl_extra_unicodes, ft_wgl_extra_glyph_names,
ft_wgl_extra_glyph_name_offsets): New arrays.
(ps_check_wgl_name, ps_check_wgl_unicode): New functions.
(ps_unicodes_init): Use them to add additional Unicode mappings.
2008-05-15 Werner Lemberg <[email protected]>
* src/psaux/t1decode.c (t1_decoder_parse_charstrings)
<op_closepath>: `closepath' without a path is a no-op, not an error
(cf. the PS reference manual).
Reported by Martin McBride.
2008-05-15 Werner Lemberg <[email protected]>
* builds/toplevel.mk (CONFIG_GUESS, CONFIG_SUB): Updated.
2008-05-15 Werner Lemberg <[email protected]>
* src/type1/t1load.c (parse_subrs): Accept fonts with a subrs array
which contains a single but empty entry. This is technically
invalid (since it must end with `return'), but...
Reported by Martin McBride.
2008-05-14 Werner Lemberg <[email protected]>
Finish fix of scaling bug of CID-keyed CFF subfonts.
* include/freetype/internal/ftcalc.h, src/base/ftcalc.c
(FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New
functions.
* src/cff/cffobjs.h (CFF_Internal): New struct. It is used to
provide global hinting data for both the top-font and all subfonts
(with proper scaling).
* src/cff/cffobjs.c (cff_make_private_dict): New function, using
code from `cff_size_init'.
(cff_size_init, cff_size_done, cff_size_select, cff_size_request):
Use CFF_Internal and handle subfonts.
(cff_face_init): Handle top-dict and subfont matrices correctly;
apply some heuristic in case of unlikely matrix concatenation
results. This has been discussed with people from Adobe (thanks
goes mainly to David Lemon) who confirm that the CFF specs are fuzzy
and not correct.
* src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.
* src/cff/cffgload.c (cff_builder_init): Updated.
(cff_decoder_prepare): Handle hints globals for subfonts.

(cff_parse_font_matrix): Use it.
* src/cff/cfftypes.h (CFF_FontDictRec): Make `units_per_em'
FT_ULong.
* docs/CHANGES: Document it.
2008-05-13 Werner Lemberg <[email protected]>
* src/winfonts/winfnt.c (fnt_face_get_dll_font, FNT_Face_Init):
Handle case `face_index < 0'.
* docs/CHANGES: Document it.
2008-05-04 Werner Lemberg <[email protected]>
First steps to fix the scaling bug of CID-keyed CFF subfonts,
reported by Ding Li on 2008/03/28 on freetype-devel.
* src/base/cff/cffparse.c (power_tens): New array.
(cff_parse_real): Rewritten to introduce a fourth parameter which
returns the `scaling' of the real number so that we have no
precision loss. This is not used yet.
Update all callers.
(cff_parse_fixed_thousand): Replace with...
(cff_parse_fixed_scaled): This function. Update all callers.
2008-05-03 Werner Lemberg <[email protected]>
* src/base/ftobjs.c (FT_Load_Glyph): Call the auto-hinter without
transformation since it recursively calls FT_Load_Glyph. This fixes
Savannah bug #23143.
2008-04-26 Werner Lemberg <[email protected]>
* include/freetype/internal/psaux.h (T1_BuilderRec): Mark `scale_x'
and `scale_y' as obsolete since they aren't used.

bug #22909.
2008-04-13 Werner Lemberg <[email protected]>
* src/psaux/psconv.c (PS_Conv_ToFixed): Increase precision if
integer part is zero.
2008-04-01 Werner Lemberg <[email protected]>

targets).
* src/base/ftobjs.c (FT_Open_Face): Don't define a variable in block
which is crossed by a `goto'.
* src/otvalid/otvalid.h (otv_MATH_validate): Add prototype.
2008-03-31 Werner Lemberg <[email protected]>
Fix support for subsetted CID-keyed CFFs.
* include/freetype/freetype.h (FT_FACE_FLAG_CID_KEYED,
FT_IS_CID_KEYED): New macros.
* src/cff/cffobjs.c (cff_face_init): Set number of glyphs to the
maximum CID value in CID-keyed CFFs.
Handle FT_FACE_FLAG_CID_KEYED flag.
* docs/CHANGES: Document it.
Fix CFF font matrix calculation and improve precision.
* src/cff/cffparse.c (cff_parse_real): Increase precision if integer
part is zero.

(ANSIFLAGS): Add _CRT_SECURE_NO_DEPRECATE.
2008-03-21 Laurence Darby <ldarby>
* src/type1/t1objs.c (T1_Face_Init): Use `/Weight'. Patch from
Savannah bug #22675.
2008-03-13 Derek Clegg <[email protected]>
* src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix named style loop.
Patch from Savannah bug #22541.
2008-03-03 Masatoshi Kimura <[email protected]>
* src/sfnt/ttcmap.c (tt_cmap14_char_map_nondef_binary,
tt_cmap14_find_variant): Return correct value.
(tt_cmap14_variant_chars): Fix check for `di'.
2008-02-29 Wermer Lemberg <[email protected]>
* docs/CHANGES: Updated.
2008-02-29 Wolf
Add build support for symbian platform. From Savannah bug #22440.
* builds/symbian/*: New files.
2008-02-21 suzuki toshiya <[email protected]>
* src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name
synthesis. For any face of a specified FOND, always the name for
the first face was used. Except of a FOND that refers multiple
Type1 font files, wrong synthesized font names are not used at all,
so this is an invisible bug. A few limit checks are added too.
* builds/mac/ftmac.c: Ditto.
2008-02-21 suzuki toshiya <[email protected]>
* builds/unix/configure.raw: Split compiler option to link Carbon
frameworks to one option for CoreServices framework and another
option for ApplicationServices framework. The split options can be
managed by GNU libtool to avoid unrequired duplication when FreeType
is linked with other applications. Suggested by Daniel Macks,
Savannah bug #22366.
2008-02-18 Victor Stinner <[email protected]>
* src/truetype/ttinterp.c (Ins_IUP): Check number of points. Fix
from Savannah bug #22356.
2008-02-17 Jonathan Blow <[email protected]>
* src/autofit/afloader.c (af_loader_load_g, af_loader_load_glyph):
Check for valid callback pointers.
2008-02-15 suzuki toshiya <[email protected]>
* src/base/ftmac.c (FT_New_Face_From_SFNT): Check the sfnt resource
handle by its value instead of ResError(), fix provided by Deron
Kazmaier. According to the Resource Manager Reference,
GetResource(), Get1Resource(), GetNamedResource(),
Get1NamedResource() and RGetResource() set noErr but return NULL
handle when they can not find the requested resource. These
functions never return undefined values, so it is sufficient to
check if the handle is not NULL.

Improvement of POSIX resource-fork accessor to load unsorted
references in a resource. In HelveLTMM (resource-fork PostScript
Type1 font bundled with Mac OS X since 10.3.x), the appearance order
of PFB chunks is not sorted; sorting the chunks by reference IDs is
required.
* include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure
type to store a pair of reference ID and offset to the chunk.
* src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to
sort FT_RFork_Ref by their reference IDs.
(FT_Raccess_Get_DataOffsets): Returns an array of offsets that is
sorted by reference ID.
2007-12-14 Werner Lemberg <[email protected]>
* src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten'
division too early; otherwise the most significant digit(s) of the
final result are lost as the value is truncated to an integer. This
fixes Savannah bug #21794 (where the patch has been posted too).
2007-12-06 Fix <[email protected]>
Pass options from one configure script to another as-is (not
expanded). This is needed for options like

There exist CFFs which contain opcodes for the Type 1 operators
`hsbw' and `closepath' which are both invalid in Type 2 charstrings.
However, it doesn't harm to support them.

`cff_op_closepath.'
(cff_argument_counts): Ditto.
(cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath)

Fix MacOS legacy font support by Masatake Yamato on Mac OS X. It is
not working since 2.3.5. In FT_Open_New(), if FT_New_Stream()
cannot mmap() the specified file and cannot seek to head of the
specified file, it returns NULL stream and FT_Open_New() returns the
error immediately. On MacOS, most legacy MacOS fonts fall into such
a scenario because their data forks are zero-sized and cannot be
sought. To proceed to guessing of resource fork fonts, the
functions for legacy MacOS font must properly handle the NULL stream
returned by FT_New_Stream().
* src/base/ftobjs.c (IsMacBinary): Return error
FT_Err_Invalid_Stream_Operation immediately when NULL stream is
passed.
(FT_Open_Face): Even when FT_New_Stream() returns an error, proceed
to fallback. Originally, legacy MacOS font is tested in the cases
of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty)
or FT_Err_Unknown_File_Format (occurs when AppleSingle header or
.dfont header is combined). Now the case of
FT_Err_Cannot_Open_Stream is included.
* src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL,
skip FT_Stream_Seek(), which seeks to the head of stream, and
proceed to unit testing of raccess_guess_XXX(). FT_Stream_Seek()
for a NULL stream causes a Bus error on Mac OS X.
(raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream
immediately if passed stream is NULL.
(raccess_guess_apple_single): Ditto.
2007-11-16 suzuki toshiya <[email protected]>
Fix for Carbon incompatibilities since Mac OS X 10.5,
proposed by Sean McBride.
* doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET.
* include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and
FT_GetFilePath_From_Mac_ATS_Name. Since Mac OS X 10.5, calling
Carbon functions from a forked process is classified as unsafe
by Apple. All Carbon-dependent functions should be deprecated.
* src/base/ftmac.c: Use essential header files <Carbon/Carbon.h>
and <ApplicationServices/ApplicationServices.h> instead of
all-in-one header file <CoreServices/CoreServices.h>.
Include <sys/syslimits.h> and replace HFS_MAXPATHLEN by Apple
genuine macro PATH_MAX.
Add fallback macro for kATSOptionFlagsUnRestrictedScope which
is not found in Mac OS X 10.0.
Multi-character constants ('POST', 'sfnt' etc) are replaced by
64bit constants calculated by FT_MAKE_TAG() macro.
For the index in the segment of resource fork, new portable
type ResourceIndex is introduced for better compatibility.
This type is since Mac OS X 10.5, so it is defined as short
when built on older platforms.
(FT_ATSFontGetFileReference): If build target is only the systems
10.5 and newer, it calls Apple genuine ATSFontGetFileReference().
(FT_GetFile_From_Mac_ATS_Name): Return an error if system is 10.5
and newer or 64bit platform, because legacy type FSSpec type is
removed completely.
(FT_New_Face_From_FSSpec): Ditto.
2007-11-01 Werner Lemberg <[email protected]>
* src/sfnt/sfobjs.c (sfnt_done_face): Check `sfnt' everywhere. This
fixes Savannah bug #21485.
2007-10-29 Daniel Svoboda <dasvo@planeta@cz>
* src/winfonts/winfnt.c (FNT_Face_Init): Check first that the driver
can handle the font at all, then check `face_index'. Otherwise, the
driver might return the wrong error code. This fixes Savannah bug
#21468.
2007-10-21 Werner Lemberg <[email protected]>
* src/sfnt/sfobjs.c (sfnt_load_face): Support bit 9 and prepare
support for bit 8 of the `fsSelection' field in the `OS/2' table.
MS is already using this; hopefully, this becomes part of OpenType
1.5.
Prepare also support for `name' IDs 21 (WWS_FAMILY) and 22
(WWS_SUBFAMILY).
2007-10-20 Werner Lemberg <[email protected]>
* src/tools/docmaker/tohtml.py (html_header_2): Fix typo.
Add `td.left' element to CSS.

2007-10-18 David Turner <[email protected]>
* include/freetype/freetype.h, src/base/ftobjs.c: Rename API
functions related to cmap type 14 support to the

FT_Get_Char_Variant_IsDefault -> FT_Face_GetCharVariantIsDefault
FT_Get_Variant_Selectors -> FT_Face_GetVariantSelectors
FT_Get_Variants_Of_Char -> FT_Face_GetVariantsOfChar
FT_Get_Chars_Of_Variant -> FT_Face_GetCharsOfVariant
Update documentation accordingly.
* src/sfnt/ttcmap.c: Stronger cmap 14 validation.
Make the code a little more consistent with FreeType coding
conventions and modify the cmap14 functions that returned a newly
allocated array to use a persistent vector from the TT_CMap14 object
instead.
(TT_CMap14Rec): Provide array and auxiliary data for result.
(tt_cmap14_done, tt_cmap14_ensure): New functions.

Introduce new string functions and the corresponding macros to get
rid of various uses of strcpy and other `evil' functions, as well as
to simplify a few things.

=========================
Tag sources with `VER-2-3-1-FINAL'.
* builds/win32/visualc/freetype.dsp,
builds/win32/visualc/freetype.vcproj: s/230/231/.
* builds/win32/visualc/index.html: s/221/231/.
* vms_make.com: Add `ftgasp'.
2007-01-30 David Turner <[email protected]>
Tag sources with VER-2-3-1 to prepare release.
* include/freetype/freetype.h (FREETYPE_PATCH): Set to 1.
* docs/VERSION.DLL, docs/release, README, Jamfile (RefDoc):
s/2.3.0/2.3.1/.
* builds/unix/configure.raw (version_info): Set to 9:12:3.
* src/autofit/aftypes.h (AF_USE_WARPER), src/autofit/afloader.c
(af_loader_load_g): Disable the warper (i.e., the light hinting
improvements) to make a 2.3.1 bugfix release before introducing a
new feature. This should give us more time to tune and improve the
warper for the next release.
* docs/CHANGES: Update accordingly.
2007-01-25 David Turner <[email protected]>
For light auto-hinting, improve glyph advance widths and resurrect
normal/full hinting to its normal quality.
* src/autofit/afhints.h (AF_GlyphHintsRec): New members `xmin_delta'
and `xmax_delta'.
* src/autofit/afhints.c (af_glyph_hints_reload): Reset `xmin_delta'
and `xmax_delta'.
* src/autofit/afloader.c (af_loader_load_g) <AF_USE_WARPER>: Replace
preprocessor conditional with if-clause, handling both light and
normal mode.
* src/autofit/afwarp.c (AF_WarpScore): Fine-tune again.
(af_warper_compute): Handle `xmin_delta' and `xmax_delta'.
2007-01-25 Werner Lemberg <[email protected]>

2007-01-25 Werner Lemberg <[email protected]>
* src/cff/cffload.c (cff_index_get_pointers): Handle last entry
correctly in a sanity check. Since this function is only used to
load local and global functions, any charstring that called the last
local/global function would fail otherwise. This fixes Savannah bug
#18867.
* docs/CHANGES: Document it.
2007-01-23 David Turner <[email protected]>
* src/truetype/ttobjs.c (tt_size_ready_bytecode): Fix typo that
prevented compilation when disabling both the unpatented and the
bytecode interpreter in the TrueType font driver.
Fix and enable the warper to improve `light' hinting mode. This is
not necessarily a final version, but it seems to work well.

Disable code.
(af_latin_hints_apply) [AF_USE_WARPER]: Handle FT_RENDER_MODE_LIGHT.

Fix various compiler warnings.
* src/truetype/ttdriver.c (tt_size_select), src/cff/cffobjs.h,
src/cff/cffobjs.c (cff_size_request), src/type42/t42objs.h:
s/index/strike_index/.
* src/base/ftobjs.c (FT_Match_Size): s/index/size_index/.
* src/gxvalid/gxvmorx5.c
(gxv_morx_subtable_type5_InsertList_validate): s/index/table_index/.

* src/sfnt/ttsbit0.h: Remove.
* src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttsbit0.c.
2007-01-12 David Turner <[email protected]>

crash with some Mac OS X .dfont files. Submitted by Masatake
Yamato.
* autogen.sh: Small fix to get it working on Mac OS X properly:
The issue is that GNU libtool is called `glibtool' on this platform,
and we must call `glibtoolize', since `libtoolize' doesn't exist.
2007-01-10 David Turner <[email protected]>
* all-sources: Tag all sources with VER-2-3-0-RC1 and
VER-2-3-0.
* Jamfile (RefDoc), README, builds/win32/visualc/freetype.dsp,
builds/win32/visualc/freetype.vcproj, docs/VERSION.DLL: Update
version number to 2.3.0.
* include/freetype/freetype.h (FREETYPE_MINOR): Set to 3.

Do not allocate interpreter-specific tables in memory if we are not
going to load glyphs with the bytecode interpreter anyway.
* src/truetype/ttgload.c (tt_loader_init): Load execution context
only if glyph is hinted.
Updated.
* src/truetype/ttobjs.h (TT_SizeRec): Add members `bytecode_ready'
and `cvs_ready'.

(tt_size_done): Move most code into `tt_size_done_bytecode'.
(tt_size_reset): Move some code to `tt_size_ready_bytecode'.
Don't extract the metrics table from the SFNT font file. Instead,
reparse it on each glyph load. The runtime difference is not
noticeable, and it can save a lot of heap memory when memory-mapped
files are not used.
* include/freetype/internal/tttypes.h (TT_FaceRec): Add members
`horz_metrics_offset' and `vert_metrics_ofset'.
* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics):
Updated.
* src/sfnt/ttcmap.c (tt_cmap4_validate): Slight optimization.
Do not load the CFF index offsets into memory, since this wastes a

Vertical_Gray_Sweep_Step, ft_black_new, ft_black_done,
ft_black_set_mode, ft_black_render): Updated.
(ft_black_init): Don't initialize `count_table'.
(ft_black_reset): Use the render pool. This saves about 6KB of
heap space for each FT_Library instance.
* src/smooth/ftgrays.c (TRaster): Replaced with...
(TWorker): This.
Remove `memory'.
(TRaster): New structure.
(RAS_ARG_, RAS_ARG, RAS_VAR_, RAS_VAR, ras, gray_render_line,
gray_move_to, gray_line_to, gray_conic_to, gray_cubic_to,
gray_render_span, gray_raster_render): Updated.
(gray_raster_reset): Use the render pool. This saves about 6KB of
heap space for each FT_Library instance.
* src/sfnt/sfobjs.c, src/sfnt/ttkern.c, src/sfnt/ttkern.h,
src/sfnt/ttmtx.c, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h,
src/truetype/ttpload.c, include/freetype/config/ftoption.h: Remove
FT_OPTIMIZE_MEMORY macro (and code for !FT_OPTIMIZE_MEMORY) since
the optimization is no longer experimental.
* src/pshinter/pshalgo.c (psh_glyph_interpolate_normal_points):
Remove a typo that results in no hinting and a memory leak with some
large Asian CFF fonts.
* src/base/ftobjs.c (FT_Done_Library): Remove a subtle memory leak
which happens when FT_Done_Library is called with still opened
CFF_Faces in it. We need to close all faces before destroying the
modules, or else some bad things (memory leaks) may happen.
2007-01-02 Werner Lemberg <[email protected]>
* src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate):
Remove compiler warning.

`gxv_kern_subtable_fmt0_pairs_validate'.
2006-12-22 David Turner <[email protected]>
* src/autofit/aflatin.c, src/truetype/ttgload.c: Remove compiler
warnings.
* builds/win32/visualc/freetype.vcproj: Add _CRT_SECURE_NO_DEPRECATE
to avoid deprecation warnings with Visual C++ 8.
2006-12-16 Anders Kaseorg <[email protected]>
* src/base/ftlcdfil.c (FT_Library_SetLcdFilter)
[FT_FORCE_LIGHT_LCD_FILTER]: Fix typo.
2006-12-15 suzuki toshiya <[email protected]>

* src/base/ftmac.c: Specialized for Mac OS X only.
* builds/unix/ftconfig.in: Fixed for ppc64 missing Carbon framework.

FSSpec/FSRef/QuickDraw/ATS availability are given to configure,
builds/mac/ftmac.c is used instead of default src/base/ftmac.c.
2006-12-15 suzuki toshiya <[email protected]>
* builds/mac/ftmac.c: Copied src/base/ftmac.c for legacy system.

2006-12-07 David Turner <[email protected]>
* src/autofit/afloader.c (af_loader_load_g): Small adjustment
to the spacing of auto-fitted glyphs. This only impacts rare

Because FT_Load_Glyph expects CID values for CID-keyed fonts, the
test for a valid glyph index must be deferred to the font drivers.
This patch fixes Savannah bug #18301.
* src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'.
* src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/cff/cffgload.c

Add a new API to support color filtering of subpixel glyph bitmaps.
In a default build, the function `FT_Library_SetLcdFilter' returns

selection for `mingli.ttf'.
2006-09-05 Werner Lemberg <[email protected]>

the Type1 stack.
Improve handling of setcurrentpoint opcode.
2006-06-25 Jens Claudius <[email protected]>
The Type 1 parser now skips over top-level procedures as required
for a `Simplified Parser'. This makes the parser more robust as it
doesn't poke around in PostScript code. Additionally, it makes the
FontDirectory hackery in src/type1/t1load.c unnecessary.

(skip_literal_string): Add FT_Error as return value.
Handle escapes better.

Insert EndianS16_BtoN and EndianS32_BtoN as workaround for Intel
Mac. The original patch was written by David Sachitano and Lawrence
Coopet, and modified by Sean McBride for MPW compatibility. Only
required data are converted; unused data are left in big endian.
* src/base/ftmac.c: Include <Endian.h> for byteorder macros for non
Mac OS X platforms.
(OS_INLINE): Undefine before definition.
(count_faces_sfnt): Insert EndianS16_BtoN to parse the header of

and fontSize at each entry of FontAssociation table in FOND
resource.
(parse_fond): Insert EndianS16_BtoN and EndianS32_BtoN to parse
ffStylOff of FamilyRecord header of FOND resource, the header,
fontSize, fontID at each entry of FontAssociation table, and
StyleMapping table.
(count_faces): Call `HUnlock' after all FOND utilization.

Public API of TrueTypeGX, OpenType, and classic kern table validator
should return `FT_Err_Unimplemented_Feature' if validation service
is unavailable (disabled in `modules.cfg'). It is originally
suggested by David Turner, cf.
http://lists.gnu.org/archive/html/freetype-devel/2005-11/msg00078.html
* src/base/ftgxval.c (FT_TrueTypeGX_Validate): Return
FT_Err_Unimplemented_Feature if TrueTypeGX validation service is
unavailable.
(FT_ClassicKern_Validate): Return FT_Err_Unimplemented_Feature if
classic kern table validation service is unavailable.
* src/base/ftotval.c (FT_OpenType_Validate): Return
FT_Err_Unimplemented_Feature if OpenType validation service is
unavailable.

* src/type1/t1afm.c (KERN_INDEX): Make it more robust.
(T1_Read_Metrics): Fix memory leak which happened when the metrics
file doesn't have kerning pairs. This fixes Savannah bug #16768.
2006-06-06 David Turner <[email protected]>
Fix memory leak described in Savannah bug #16759.
We change `ps_unicodes_init' so that it also takes a
`free_glyph_name' callback to release the glyph names returned by
`get_glyph_name'
* include/freetype/internal/services/svpscmap.h (PS_Glyph_NameFunc):
Renamed to ...
(PS_GetGlyphNameFunc): This.
(PS_FreeGlyphNameFunc): New typedef.
(PS_Unicodes_InitFunc): Add variable for PS_FreeGlyphNameFunc.
* src/cff/cffcmap.c (cff_sid_to_glyph_name): Use `TT_Face' for first
argument.

PS_FreeGlyphNameFunc and use it.
2006-06-04 David Turner <[email protected]>
* src/base/ftutil.c (ft_mem_qrealloc): Fix the function to accept
`item_size == 0' as well -- though this sounds weird, it can
theoretically happen. This fixes Savannah bug #16669.
* src/pfr/pfrobjs.c (pfr_face_init): Fix the computation
of `face->num_glyphs' which missed the last glyph, due to
the offset-by-1 computation, since the PFR format doesn't
guarantee that glyph index 0 corresponds to the `missing
glyph. This fixes Savannah bug #16668.
2006-05-25 Werner Lemberg <[email protected]>
* builds/unix/unix-cc.in (LINK_LIBRARY): Don't comment out
`-no-undefined'. Reported by Christian Biesinger.
2006-05-19 Brian Weed <[email protected]>

have debug information, and debug libraries use `C7 compatible'
debug info.
2006-05-19 suzuki toshiya <[email protected]>

the second part of Savannah bug #16590.
2006-05-18 Werner Lemberg <[email protected]>
* src/truetype/ttgload.c (TT_Load_Composite_Glyph)
[FT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again.
2006-05-17 David Turner <[email protected]>
This is a major patch used to drastically improve the performance of
loading glyphs. This both speeds up loading the glyph vectors
themselves and the auto-fitter module.
We now use inline assembler code with GCC to implement `FT_MulFix',
which is probably the most important function related to the
engine's performance.
The resulting speed-up is about 25%.
* include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields
`cursor' and `limit'.
* src/autofit/afangles.c (af_corner_is_flat, af_corner_orientation):
New functions.
(AF_ATAN_BITS, af_arctan, af_angle_atan): Comment out.
[TEST]: Remove.
* src/autofit/afcjk.c (AF_Script_UniRangeRec): Comment out test
code.
* src/autofit/afhints.c (af_axis_hints_new_segment): Don't call
`FT_ZERO'
(af_direction_compute, af_glyph_hints_compute_inflections): Rewritten.
(af_glyph_hints_reload: Rewrite recognition of weak points.
* src/autofit/aflatin.c (af_latin_hints_compute_segments): Move
constant values out of the loops.
* src/autofit/aftypes.h: Updated.
* src/base/ftcalc.c (FT_MulFix): Use inline assembler code.
* src/base/ftoutln.c (FT_Outline_Get_Orientation): Use vector
product to get orientation.
* src/gzip/ftgzip.c (ft_get_uncompressed_size): New function.
(FT_Stream_OpenGzip): Use it to handle small files directly in
memory.
* src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_ConvEexecDecode):
Improve performance.
* src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and
`limit'.
(TT_Load_Glyph_Header, TT_Load_Simple_Glyph,
TT_Load_Composite_Glyph): Updated. Add threshold to protect against
exceedingly large values of number of contours. Speed up by
reducing the number of loops.
* src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix.
* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold
used to detect rogue clients from 4 to 16. This is to prevent some
segmentation faults with fonts like `KozMinProVI-Regular.otf' which
comes from the Japanese Adobe Reader Asian Font pack.
2007-05-17 Werner Lemberg <[email protected]>
* src/cff/cffload.c (cff_font_done): Deallocate subfont array. This
fixes the first part of Savannah bug #16590.
2006-05-16 Werner Lemberg <[email protected]>
* docs/PROBLEMS: Updated icl issues.
